A 32 channels charge integrating ADC based on digital signal integration

摘要

A digital charge integrator with programmable gate width and range has been designed for use in the KLOE drift chamber front-end chain. The system has a resolution of 9 bits ranging from 600 fC/count up to approximate to 76pC and integration time ranging from 100ns to about 13 mu s. Thirty-two channels have been packaged in a single VME 9U board. (c) 2006 Elsevier B.V. All rights reserved.
